bpo-32327: Revert loop.run_in_executor behaviour: return a Future. (#5392) 
I've run some tests on 3.7 asyncio and it appears that too many
things assume that run_in_executor returns a Future.

991adca012 bpo-30048: asyncio: fix Task.cancel() was ignored. (GH-1097) 
when there are no more `await` or `yield (from)` before return in coroutine,
cancel was ignored.

example:

    async def coro():
        asyncio.Task.current_task().cancel()
        return 42
    ...
    res = await coro()  # should raise CancelledError

a0c1ba608e Issue #28544: Implement asyncio.Task in C. 
This implementation provides additional 10-20% speed boost for
asyncio programs.

The patch also fixes _asynciomodule.c to use Arguments Clinic, and
makes '_schedule_callbacks' an overridable method (as it was in 3.5).
